Balancing Wireless Sensing Performance and Privacy Protection With Multi-Antenna Systems
- Published
- Record updated
Summary
The paper studies privacy risks in Wi-Fi-based wireless sensing, where signals that reveal movement status and sleep quality can be intercepted by unauthorized users. It proposes a multi-antenna signal processing strategy at the physical layer and models sensing as a communication task to define a sensing rate region. It characterizes two boundary points, P_OS and P_OPP, and a secure sensing rate R_PP, validated through numerical simulations.
